TUFT-YARN SPOOL FOB LOOKS.

Application led September 28, 1922. Serial No. 591,118.

To all whom t may concern:

Be it known that I, HARRY' D. CLINTON, a citizen of the United States, residing at Johnson City, in the county of Broome and State of New York, have invented certain new and useful Improvements in Tuft-Yarn Spools for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spools and more particularly to the heads of spools used on tuft yarn frames and carriers 1n wide or narrow looms as used especially in the manufacture of Axminster carpets and rugs in which a stron durable and non-breakable spool and hea are essential to the production of an even, smooth, uniform and regular weave in thefabric.

S ools heretofore used in the manufacture of minster carpets and rugs, the value of which depends largely upon the fineness and evenness of texture, have been made either of wood or steel, neither of which however, has proven satisfactory. `Spools with wooden heads are not sufficiently strong to endure the severe strain, wear and friction necessarily placed upon them, and therefore split or become so badly dented and worn after slight use as to permit the head of the spool to be caught and tripped by the spring tension regulator bearing against the outer peripheral edge thereof, causing what is known as a low row or imperfection in the rug, or else breaking the yarn in two, thus frequently making it necessary to stop the loom to accomplish repair and replacement, with incident loss of time and expense. Steel heads and steel spools are likewise impracticable, since the metal becomes heated and expands, causing the spool to bind or warp, producing unevenness in the -texture of the rug and necessitating frequent replacement. The weight of a steel spool is also an additional objection. Considerable time is consequently lost through present day devices, and much otherwise avoidable expense is involved in the manufacture of these carpets. It has also been proposed to construct spool heads composed of disks of re-enforced vulcanized fibre for use in the manufacture of fabrics of silk, cotton, wool and the like, and I therefore make no broad claim to a vulcanized fibre head oer. se.

The object of this invention is to overcome the objections above noted, and to provide a tuft yarn spool with a hard, nonbreakable head which will not wear away, warp, become dented nor split, and which will last as long as the loom itself, permitting an uninterrupted, even, smooth, uniform and regular weave of the carpet, and which 1n addition will be light, durable and strong, impervious to heat caused by friction, thus supplying to the market and to manufacturers, a dependable spool which will greatly increase the eiiiciency of carpet Weaving machines and reduce the expense heretofore involved in the manufacture of Axminster carpets and rugs.

Another object of my invention is to provide a spool of the character referred to, in which the head of vulcanized hard fibre is so securely fastened to the soft-wood barrel or loom of the spool that it may not become loosened nor removed therefrom without breaking the spool apart.

My invention essentially differs from ordinarv spool devices, inasmuch as it-is designed especially as a tuft yarn spool peculiarly adapted for use in the manufacture of Axminster carpets and rugs, inwhich the head, upon which the value of production so largely depends, comprises composite ma.- terials treated in such manner as to produce a radical, new and requisite improvement over devices heretofore known and employed in the carpet industry.

My invention will first be hereinafter more particularly described, with reference lto the accompanying drawings, which are to be taken as a part of this specification and then pointed out in the yclaims at the end of the description.

In said drawings, Fig. 1 is a longitudinal elevation of my improved tuft yarn spool;

Fig. 2 is a. longitudinal sectional elevation of broken away end portions of the spool;

Fig. 8 is a sectional side elevation taken on` the line 3-3 of Fig. 2;

Fig. 4 is a side elevation of the tapered fastener plug; and

Fig. 5 1s a sectional view of one end of the spool barrel and a fragment of the head in position for assembling.

Referring to the drawings in which like reference numerals are used to denote corresponding parts throughout the several views, l denotes an ordinary soft-wood barrel of a tuft yarn spool, opposite ends of the barrel being provided with sockets or recesses 2 about two inches in depth, the outermost portions or extremities of the barrel being counter bored to form annular peri heral projections or flanges 3.

o the opposite ends of the barrel 1 are secured hard vulcanized libre spool heads 4, preferably composed of a multiplicity of very thin layers of cloth, pressed and vulcanized together by the use of z1nc, said heads being providedwith annular grooves 5 adapted to register with and snugly receive the annular flanges 3 provided on opposite ends of the soft-Wood barrel 1, cement or glue being utilized to hold the two elements together, such mode of attachment ositivelv preventing the soft-wood barrel rom splitting When a lateral strain is applied to the vulcanized fibre head. Lateral strains on spools as heretofore constructed invariabl cause the soft-wood barrels to split, winch is a difficulty continuously eX- perienced by carpet manufacturers, and the main objection to the ordinary spools commonly used. The head 4 is also provided with a central tapering or frusto-conical orifice 6, the inner circumferential edge thereof registering with the outer circumferential edge of the socket or recess 2 in the barrel 1.

A wooden fastening plug comprising a..

body portion 7 having a tapered-or frustoi conlcal head 8 adapting it to fit snugly within the tapering or frusto-conical socket or recess formed by the union of the head 4 with the barrel 1, bringing the central orifice 6 into registration with the socket 2, is coated with cement or glue and driven into the socket 2, its tapered head 8 seating within the tapering orifice 6 in the head 4, thus firmly and securely binding the head 4 to the barrel 1, as illustrated in Fig. 2. The plug is preferably about two inches in length, presenting a much larger glue-coated surface area to the inner wall surface of the socket 2 than is usual in spools of ordinary construction, which fact in connection with the tapered head 8 reventing outward movement of the spool liead 4, so firmly secures the spool head to the barrel as to render subse uent separation impossible unless the spoo is broken apart.

The fastening plug secured in one end of the spool l is provided with a central, longitudinal bore 9, adapting a stationary, projecting guide or axis pin 10 to be inserted within the plug and glued or otherwise secured in place. The fastening plug secured in the opposite end of the spool 1, is likewise provided with a longitudinal central bore, the innermost end being counter bored to larger diameter as illustrated in Fig. 2, to accommodate a retractable plunger or guide pin 11, carrying an ordinary encircling coiled spring 12. The retractable pin 11 is shouldered near its innermost end, the sprin l2 being interposed between said shoul er and the terminus of the socket 2, which may be likewise counter bored to proper `diameter to accommodate one end of the spring, said spring tensionably holding the plunger 11 normally extended through the spool head. Since the spool guides or pins 10 and l1 are thus carried within the fastening plugs,'which are essentially a part of the spool head, it may be said that/such elements are self contained within the hard vulcanized fibre head.

From the foregoing, it will be readily understood that I have provided a novel and highly useful improvement in tuft yarn spools, and that my invention removes all theobjectionable features involved in spools of ordinary construction, supplying particularly to manufacturers of Axminster carpets and rugs, a dependable, non-breakable, even running' spool, which is so essential to the peculiar needs of such industry.
